代码示例

代码示例来源：origin: org.jsoup/jsoup

/**
 * Set the form element's value in each of the matched elements.
 * @param value The value to set into each matched element
 * @return this (for chaining)
 */
public Elements val(String value) {
  for (Element element : this)
    element.val(value);
  return this;
}

代码示例来源：origin: org.jsoup/jsoup

/**
 * Get the form element's value of the first matched element.
 * @return The form element's value, or empty if not set.
 * @see Element#val()
 */
public String val() {
  if (size() > 0)
    return first().val();
  else
    return "";
}
